CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of application Ser. No. 16/376,545, which issued as U.S. Pat. No. 10,859,054, which is a continuation of PCT/US2018/003502, which claims priority from provisional applications 62/562,713, 62/561,751, and 62/552,065.

FIELD

The present invention is directed to a rechargeable jump starting device having a highly electrically conductive cable connecting device (e.g. cam-lock battery cable connecting devices) for detachably connecting positive and negative battery cables to the rechargeable jump starting device. For example, the rechargeable battery jump starting device is for use in jump starting batteries of automobiles, trucks, heavy equipment, commercial vehicles, commercial equipment, buses, commercial trucks, front loaders, dozers, back hoes, excavators, rollers, fork lift, specialized commercial equipment, logging equipment, airplanes, jets, boats, and other vehicles or equipment using a starting battery.

BACKGROUND

There exists U.S. Pat. No. 9,007,015 filed Jul. 8, 2014 to Nook et al. entitled Portable Vehicle Battery Jump Start Apparatus with Safety Protection. This battery jump start apparatus utilizes a lithium ion battery pack. In this type of apparatus, there exists a need to maximize conductivity from the battery pack of the apparatus to the vehicle battery of the vehicle being jump started. For successful vehicle jump-starts, there are two main factors dictating the results. The first factor is the amount of power provided by the lithium ion battery pack, and the second factor is the maximum conductivity. You need both factors to have the best chance to jump-start big engines. One factor without the other factor is not enough.

Further, there exists PCT application no. PCT/US2016/024680 filed on 29 Mar. 2016 (published 17 Aug. 2017 as WO 2017/138963 A1) entitled Battery Assembly Device. The battery assembly device disclosed provides an enhanced electrically conductive battery assembly for use, for example, in a battery jump start apparatus.

In addition, there exists PCT application no. PCT/US2017/017289 filed on 10 Feb. 2017 (published 17 Aug. 2017 as publication no. WO 2017/139524 A1) entitled Battery Connector Device for a Battery Jump Starting Device. The battery assembly device disclosed provides an enhanced electrically conductive battery assembly for use, for example, in a battery jump start apparatus.

Also, currently there exist heavy duty battery jump starters using conventional lead acid batteries. The jump starters are heavy in weight (e.g. hundreds of pounds) and large dimensionally requiring the jump starter to be moved around using a fork lift. Thus, the current battery jump starters are not portable in any manner.

There exists a need for an improved portable battery jump starting device having significantly increased power output (i.e. high power output), reduced weight, and reduced size to replace conventional units.

There also exists a need for an improved portable battery jump starting device having detachable cables (e.g. positive cable, negative cable) to reduce the overall weight of the portable battery jump starting devices when moving or transporting same, and to make storage of the portable battery jump starting device and cables easier and more convenient. For a portable jump starting device having a high power output, the cable connectors for making the cables detachable must be configured and designed to handle high power output from the portable jump starting device through the connectors to the detachable cables (e.g. battery cables).

The cover 12 is provided with the resilient sealing cap 22, including left sealing cap 22 a for sealing left port 20 a and right sealing cap 22 b for sealing right port 20 b during non-use of the battery jump starting device 10.

The left side of the battery jump starting device 10 is also fitted with a pair of light emitting diodes 28 (LEDS) for using the battery jump starting device 10 as a work light. For example, the LEDs 28 are dual 1100 Lumen high-intensity LED floodlights), as shown in FIGS. 1, 4, and 8 . The LEDs 28 are configured to have seven (7) operational modes, including 100% intensity, 50% intensity, 10% intensity, SOS (emergency protocol), Blink, Strobe, and Off.

The battery jump starting device 10 is fitted with a heat sink 29 (FIG. 1 ) for dissipating heat from the LEDs 28. For example, the heat sink 29 is made of a heat conductive material (e.g. molded or die cast aluminum heat sink). The rib design facilitates the heat sink 29 transferring heat to the surrounding atmosphere to prevent the LEDs 28 from overheating.

The battery jump starting device 10 is shown in FIG. 1 without any battery cables having clamps for connecting the battery jump starting device 10 to a battery of a vehicle to be jump started. The battery jump starting device can be configured to detachably connect to a set of battery cables having battery clamps (e.g. positive battery cable with a positive clamp, negative battery cable with a negative clamp). Alternatively, the battery jump starting device can be fitted with battery cables having clamps hard wired to the device and non-detachable.

For example, the left side of the battery jump starting device 10 is provided with a POSITIVE (+) cam-lock 24 a and a NEGATIVE (−) cam-lock 24 b, as shown in FIG. 4 . The cam-locks 24 a, 24 b include receptacles 25 a, 25 b configured for detachably connecting with connecting end 56 a (FIG. 11 ) of the positive battery cable 56 and the connecting end 58 a of negative battery cable 58, respectively. The cam-locks 24 a, 24 b are fitted with sealing caps 26 for closing and sealing the receptacles 25 a, 25 b of the cam-locks 24 a, 24 b, respectively, during non-use of the battery jump starting device 10, as shown in FIG. 1 .

The power circuit 30 of the battery jump starting device 10 is shown in FIG. 9 .

The power circuit 30 comprises two (2) separate Lithium ion (Li-ion) batteries 32 (e.g. two (2) 12V Li-ion batteries) connected to the control switch 18 via a pair of cable sections 34, 36 (e.g. insulated copper cable sections), respectively. The control switch 18 is connected to the reverse currently diode array 48 (i.e. reverse flow protection device) via the cable section 40, and the control switch 18 is connected to the smart switch 50 (e.g. 500 A solenoid device) via cable section 42, as shown in FIG. 9 .

The reverse current diode array 48 is connected to the one battery 32 via cable section 44, and the smart switch 50 is connected to the other battery 32 via cable section 46, as shown in FIG. 9 .

The positive battery cable 56 having a positive battery clamp 60 is detachably connected to the positive cam-lock 24 a (FIGS. 1 and 9 ) connected to the reverse current diode array 48 via cable section 52.

The negative battery cable 58 having a negative battery clamp 62 is detachably connected to the negative cam-lock 24 b (FIGS. 1 and 9 ) connected to the smart switch 50 via cable section 54.

In the above described first embodiment of the power circuit 30, the electrical components of the power circuit 30 are connected together via cable sections (e.g. flexible insulated copper cable sections).

A second embodiment of the battery jump starting device 110 has the internal electronic assembly shown in FIGS. 20-25 . In the second embodiment, the outer cover is shown removed in FIGS. 16-25 . The cover for the battery jump starting device 110 is the same as the cover 12 of the battery jump starting device 10 shown in FIG. 1-8 .

In the second embodiment of the battery jump starting device 110 compared to the battery jump starting device 10 shown in FIGS. 1-8 , the cable sections 34, 36, 40, 42, 44, 46 (FIG. 9 ) are replaced with a highly electrically conductive frame 170.

The battery jump starting device 110 comprises a pair of 12V Li-ion batteries 132 directly connected to the highly electrically conductive rigid frame 170. Specifically, the tabs of the Li-ion batteries are soldered to the highly electrically conductive rigid frame 170.

The highly electrically conductive rigid frame 170 is constructed of multiple highly electrically conductive rigid frame members 134, 136, 140, 142, 144, 146, 152, 154 connected together by mechanical fasteners (e.g. copper or aluminum nut and/or bolt fasteners) and/or soldering. For example, the highly electrically conductive rigid frame members are made of highly electrically conductive rigid copper rods. Alternatively, the highly electrically conductive rigid copper or aluminum rods can be replaced with highly electrically conductive rigid copper or aluminum plates, bars, rods, tubing, or other suitably configured highly electrically conductive copper or aluminum material (e.g. copper or aluminum stock material). The highly electrically conductive rigid frame members 134, 136, 140, 142, 144, 146 can be insulated (e.g. heat shrink) in at least key areas to prevent any internal short circuiting.

The highly electrically conductive rigid frame members can be configured with flattened end portions (e.g. flattened by pressing) each having a through hole to provide part of a mechanical connection for connecting successive or adjacent highly electrically conductive rigid frame members and/or electrical components together using a highly electrically conductive nut and bolt fastener (e.g. copper bolt and nut). Alternatively, a highly electrically conductive rigid frame member can be formed into a base (e.g. plate or bar portion) for an electrical component.

For example, the reverse flow diode assembly 148 has three (3) base portions, including 1) an upper highly electrically conductive rigid bar 148 a (FIG. 16 ) having a flattened end portion 148 aa connected to the flattened end portion 144 a of highly electrically conductive rigid frame member 144 using a highly electrically conductive fastener 206 (e.g. made of copper or aluminum) having a highly electrically conductive bolt 206 a and highly electrically conductive nut 206 b; 2) a lower highly electrically conductive rigid bar 148 b made from a flattened end portion of highly electrically conductive rigid frame member 144; and 3) a center highly electrically conductive rigid bar 148 c made from a flattened end portion of highly electrically conductive rigid frame member 152.

As another example, the smart switch 150 (FIG. 16 ) comprises a highly electrically conductive rigid plate 150 a serving as a base supporting the solenoid 150 b. The highly electrically conductive rigid plate 150 a is provided with through holes for connecting highly electrically conductive rigid frame members to the smart switch 150 (e.g. highly electrically conductive rigid frame member 142) using the highly electrically conductive fastener

The stock material (e.g. copper or aluminum plate, bar, rod, and/or tubing) selected for construction of the highly electrically conductive rigid frame 170 has substantial gauge to provide highly electrical conductivity and substantial rigidity. The “rigid” nature of the highly electrically conductive rigid frame 170 provides the advantage that the highly electrically conductive rigid frame remains structurally stiff and stable during storage and use of the battery jump starting device 110.

For example, the highly electrically conductive rigid frame 170 is designed and constructed to sufficiently prevent flexing, movement, bending and/or displacement during storage or use so as to prevent electrical shortages of the highly electrically conductive rigid frame touching other internal electrical components or parts of the electronic assembly. This “rigid” nature is important due to the high electrically conductivity path or pathway of electrical power from the Li-ion batteries flowing through the power circuit and reaching the battery clamps. It is a desired goal and feature of the present invention to conduct as much power as possible from the Li-ion batteries to the battery being jump started by the battery jump starting device by reducing or minimizing any electrical resistance by using the heavy duty and highly electrically conductive rigid frame 170 arrangement disclosed.

As an alternative, the highly electrically conductive rigid frame can be constructed as a single piece having no mechanically fastened joints. For example, the highly electrically conductive rigid frame can be made from a single piece of stock material and then formed into the highly electrically conductive rigid frame. For example, a billet of highly electrically conductive copper or aluminum can be machined (e.g. milled, lathed, drilled) into the highly electrically conductive rigid frame. As another example, a copper or aluminum sheet or plate can be bent and/or machined into the highly electrically conductive rigid frame. As a further alternative, the highly electrically conductive rigid frame can be metal molded (e.g. loss wax process).

As another alternative, the highly electrically conductive rigid frame is made of multiple highly electrically conductive rigid frame members connected together into a unitary structure. For example, the highly electrically conductive rigid frame is made of highly electrically conductive sections of stock material (e.g. copper rod, plate, bar, tubing), which are bent and soldered and/or welded together.

The battery jump starting device 110 further comprises a resistor array 202 (e.g. 12 V 5A XGC) comprising a printed circuit board (PCB) 202 a serving as a base supporting an array of individual resistors 202 b, as shown in FIGS. 17 and 19 . The PCB 202 a also supports the dual 2.1 amp (A) USB OUT ports 120 c, 120 d, the 18A 12V XGC OUT port 120 e, and the 5A 12V XGC IN port 120 f.

The left side of the battery jump starting device 110 is also fitted with a pair of light emitting diodes 128 (LEDS) for using the battery jump starting device 110 as a work light. For example, the LEDs 128 are dual 1100 Lumen high-intensity LED floodlights), as shown in FIG. 16 . The LEDs 128 are configured to have seven (7) operational modes, including 100% intensity, 50% intensity, 10% intensity, SOS (emergency protocol), Blink, Strobe, and Off.

The battery jump starting device 110 is fitted with a heat sink 129 (FIG. 16 ) for dissipating heat from the LEDs 128. For example, the heat sink 129 is made of a heat conductive material (e.g. molded metal plate). The heat sink 129 is provided with ribs 129 a transferring heat to the surrounding atmosphere to prevent the LEDs 128 from overheating.

The battery jump starting device 110 is shown in FIG. 16 without any battery cables having clamps for connecting the battery jump starting device 110 to a battery of a vehicle to be jump started. The battery jump starting device can be configured to detachably connect to a set of battery cables having battery clamps (e.g. positive battery cable with a positive clamp, negative battery cable with a negative clamp). Alternatively, the battery jump starting device can be fitted with battery cables having clamps hard wired to the device and non-detachable.

For example, the left side of the battery jump starting device 110 is provided with a POSITIVE (+) cam-lock 124 a and a NEGATIVE (−) cam-lock 124 b, as shown in FIG. 16 . The cam-locks 124 a, 124 b include receptacles 125 a, 125 b configured for detachably connecting with connecting end 56 a (FIG. 11 ) of the positive battery cable 56 and the connecting end 58 a of negative battery cable 58, respectively. The cam-locks 124 a, 124 b can be fitted with sealing caps for closing and sealing the receptacles 125 a, 125 b of the cam-locks 124 a, 124 b, respectively, during non-use of the battery jump starting device 110.

The positive cam-locks 24 a, 124 a can have the same construction as the negative cam-locks 24 b, 124 b. The cam-locks 24 a, 24 b detachably connect the battery cables 56, 58 (FIG. 9 ) to the power circuit 30 of the battery jump starting device 10. The cam-locks 124 a, 124 b are mechanically anchored to the base plate (FIG. 16 ) of the base plate 150 a of the smart switch 150. The construction of the cam-locks 24 a, 124 a, 24 b, 124 b will be described using cam-lock 27 as an example.

The cam-locks 24 a, 24 b, 124 a, 124 b can be used for other applications for detachably connecting a conductive electrical cable to an electronic device.

The details of the construction of the cam-lock 27 is shown in FIG. 32 . Again, the construction for the cam-locks 24 a, 124 a, 24 b, 124 b can be the same as or similar to cam-lock 27 (FIG. 32 ).

The cam-lock 27 comprises a male cam-lock end 27 a and a female cam-lock end 27 b for detachable connecting the battery cables 56, 58 (FIG. 10 ), respectively, to the battery jump starting device 10, 110.

The male cam-lock end 27 a comprises a pin 27 aa having a tooth 27 ab. The female cam-lock end 27 b comprises a receptacle 27 ba having a slot 27 bb together located in a hex portion 27 bc. The receptacle 27 ba is configured to accommodate the pin 27 aa and tooth 27 ab of the male cam-lock end 27 a. Specifically, the pin 27 aa and tooth 27 ab of the male cam-lock end 27 a can be inserted (FIG. 32 ) into the receptacle 27 ba and slot 27 bb a fixed distance until the tooth 27 ab contacts an interior surface of the internal thread of the female cam-lock 27 b to be described below. The male cam-lock end 27 a can be rotated (e.g. clockwise) to tighten within the female cam-lock end 27 b until the end face portion 27 ac of the male cam-lock end 27 a engages with the end face portion 27 bd of the female cam-lock end 27 b. The more the cam-lock 27 is tightened, the better the electrical connection is between the male cam-lock end 27 a and the female cam-lock end 27 b.

The male cam-lock end 27 a is fitted with a rubber molded cover 31, as shown in FIG. 32 , to insulate and improve the grip on the male cam-lock end 27 a. The highly electrically conductive cable 56 is electrically and mechanically connected to the male cam-lock end 27 a, and is fitted through a passageway in the rubber molded cover 31.

The assembly of the male cam-lock 27 a is shown in FIG. 35 . The male cam-lock 27 a is provided with a thread hole 37 for accommodating Allen head fastener 39. The one end of the male cam-lock 27 a is provided with a receptacle 27 ad for accommodating the copper or aluminum sleeve 41 fitted onto the end of the inner conductor 56 a of the battery cable 56. The copper or aluminum sleeve 41 is soldered onto the inner conductor 56 a using solder 43.

The copper or aluminum sleeve 41 is fitted into the receptacle 27 ad of the male cam-lock end 27 a, as shown in FIG. 36 . When the copper or aluminum sleeve 41 is fully inserted into the receptacle 27 of the male cam-lock end 27 a, as shown in FIG. 37 , then the Allen head fastener is threaded into the threaded hole 37 and tightened, as shown in FIG. 38 .

It is noted that the inner end of the Allen head fastener makes an indent 45 (FIG. 35 ) when sufficiently tightened to firmly anchor the copper or aluminum sleeve 41 and inner conductor 56 a of the battery cable 56 to mechanically and electrically connect the cable 56 to the male cam-lock end 27 a.

The rubber molded cover 31 is provided with one or more inwardly extending protrusions 31 a (FIG. 32 ) cooperating with one or more slots 27 ae in an outer surface of the male cam-lock end 27 a (FIG. 32 ).

Again, the male cam-lock end 27 a and the female cam-lock end 27 b are configured so as to tighten together when rotating the male cam-lock end 27 a when inserted within the female cam-lock end 27 b.

The female cam-lock end 27 b, as shown in FIG. 40 , is provided with the receptacle 27 ba and slot 27 bb for accommodating the end of the male cam-lock end 27 a. The slot 27 bb is provided with a surface 27 bba serving as a stop for the tooth 27 ab of the male cam-lock end 27 a. The receptacle 27 ba is provided with inner threading 27 baa for cooperating with the tooth 27 ab of the male cam-lock end 27 a to provide a threaded connection therebetween. Specifically, the tooth 27 ab engages with the surface 27 bba and is stopped from being further inserted into the receptacle 27 ba of the female cam-lock end 27 b. When the male cam-lock end 27 a is rotated, the tooth 27 ab engages and cooperates with the inner threading 27 baa of the receptacle 27 ba of the female cam-lock end 27 b to begin tightening the male cam-lock end 27 a within the female cam-lock end 27 b with the tooth 27 ab riding against an edge of the inner thread 27 baa. The male cam-lock end 27 a is further rotated to further tighten the connection with the female cam-lock end 27 b. When the face 27 ac (FIG. 32 ) of the male cam-lock end 27 a engages with the face 27 bd of the female cam-lock end 27 b, then the cam-locks ends 27 a, 27 b are fully engage and rotation is stopped.

The female cam-lock end 27 b (FIGS. 40 and 41 ) is provided with inner threading 27 bf (FIG. 40 ) to accommodate the bolt 47 and lock washer 49 (FIG. 41 ) for connecting the female cam-lock end 27 b to the battery jump starting device 10 (e.g. connects to base plate of smart switch 50 (FIG. 9 )).
